I did go to many meetings of the American Physical Society; most... most of the meetings in New York and all the meetings in Washington which were held at the time of cherry blossoms, which was delightful. And in addition to the Physical Society meetings in Washington, there were small meetings which were organized by George Washington University and by the Carnegie Institution of Washington, jointly. Carnegie Institution had as its main physicist were Tuve who had built an accelerator to get protons up to about a million electron volts with very accurately controlled energy, and they were doing beautiful experiments on the scattering of protons by hydrogen, that is protons by protons, and we learned a great deal about nuclear forces from these experiments. They were carefully evaluated by Gregory Breit and his students. But what I was... wanted to talk about were these meetings. They were about one week long, a little earlier in spring than the Physical Society and there were maybe 20 physicists at each of these meetings, usually... were mostly theorists, but sometimes a couple of experimenters and then later on astrophysicists, but it was mainly theory. And we discussed very much nuclear theory. We discussed the problem of high energy electrons penetrating more matter than... than anybody thought believable. We discussed quantum electrodynamics, Breit was very interested in that.

[Q] And this was organized by Teller and...

By Teller, Gamow and Tuve.
